Has God spoken? If the answer is no, then all religion is informed guesswork, following the clues we think the divine being has left in creation, human personality, the cosmos and whatever else we think points towards God. The trouble is, if we don’t know what God is like, we don’t know what points in his direction. If you don’t know where London is, then you have no idea whether any signs which say ‘London’ are pointing to London, or to Nempnett Thrubwell. So either you bet on all the religions at once (Bahai), or you have to stay neutral about all of them. As Homer Simpson puts it “what if we’ve chosen the wrong religion? Every week we’re just making God madder and madder.”
